T'bird 54 won't sync after FW update

[redshift]

Hi Patrick, I would not have posted without first checking for any bearing binding, or wiring issues. I did another update, same result, and even tried a third motor to no avail. I am 1000% positive the update is to blame. The 54 has worked flawlessly since late summer-ish last year, and has not seen over 30A. It's being used in a 30 oz SuperCub.

I'm trying to locate the receipt, not having much luck. Do I need to contact the retailer for a record of receipt to do a return?

EDIT: was purchased from All E RC August 6, 2009, I can request a reprint if need be?
